Be Ait known that fI, ALFRED "MARKS, a citizen of the United States, residing .at Brooklyn, in the countyofKings and State of New York, haveinvented certain new and usefulImprovements in aJGlosure F astener, of which the following isa specification. y

This inventionrelatesA to J new fand `usefu improvements A'-in closure #fasteners `and has g for its prinipaliobject to provide a simple and Ieificient'4de-vice-which is adapted to be associated with a sliding closure such as a door or a window for normally holding the same in a closed position. Y

A further object of the invention is to provide a closure fastener of the above mentioned character, which is automatic in its operation and will enable the closure to be readily opened without any diliiculty.

A still further object of the invention is to provide a closure fastener of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is designated.

Other object-s and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals designate like 'parts 'throughout the same:

Figure l is a fragmentary front elevation of a closure for a receptacle showing my fastener associated therewith.

Figure 2 is a sectional view taken approximately on line 2--2 of Figure l.

Figure 3 is a detail perspective view of a portion of the closure showing the opening provided therein for receiving the fastener, and y Figure 4 is a' fragmentary sec-tional view of a window with my invention associated therewith.

lu the drawing wherein for the purpose of illustration is shown the preferred cn1bodiment of my invention, the numeral l designates a receptacle of any well known coustruction, the same being provided with a curved top 2, the same being provided with an opening 3 whereby access to the receptacle may be had. A closure 4 for the open` ing 3 `is adapted for slidable movement betweenk the guide strips 5 and 6 respectively which are secured to the curved top 2 adm 1924. Seral N0. 719,386.

The forward! portion of the elosure-4 1s provided with suitable handles 8Wfor facili tating 'the sliding movement thereofto uncover or close the openingbasjthe ca se'anayf lbeand arranged inthe'forward porti-on of the vcover or closure 4 4adjacent, the ends lthereof are the openings such as are illusti'ated at 9 in thedrawing. .Thisgishniore clearly illustratedlin.Figure f3.' A"The pur? pose of the opening 9 in the forward lower portion of the closure will hereinafter be F more fully described.'

Flach of the guide strips is provided with an opening l() in the forward end thereof and adapted to be seated in said opening of each strip is the spherical member 11. Each of these spherical members extends through each of the openings provided in thestrip and kis adapted for engagement with thev openings 9 provided in the forward lower portions of the closure 4. For the purpose of normally holding the spherical member in engagement with the openings 9 whereby afastener for the closure is provided, I provide each Vstrip with a pair'of bolts 12 and 13 which extend laterally from thestrip on opposite sides of the opening l] and a flat spring member 14 is adapted for slidable movement on the bolt and engages the outer portion of the spherical member 11 to hold the same in engagement with the openings 9 in the closure 4.

Normally the parts are arranged as shown in Figure 2 of the drawing and thesprings 14 urge the spherical members 1l into engagement with the openings 9 whereby a fastener for the closure 4 is provided. Vhen the closure 4 is moved to an open position, the spherical members l1 will move out wardly out of engagenient with the openings 9 and force the dat springs out-wardly and simultaneously placing the same under tension. `When the closure 4 is returned to its normal position, the spherical member 1l will again seat in the openings 9 and hold the closure in a closed position.

ln Figure 4 of the drawingthe invention is shown as associated with the sliding window 'l5 and the guide rails 16 therefor. The windowV sash is provided with a metal plate 17 in which an opening or recess 1S is provided for the reception of the spherical member 19, the latter extending through a The simplicity of .my device enables the same to be readily and easilyplaced in position for use and Will be'strong and durable as well as inexpensive.

Vhile I have shown the preferred embodilnent of my invention, it is to be nnderstood that various changes in the size, shape and arrangement of parts may be resorted to Without departing from the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what I claim is In combination, a movable member, a stationary member, both of said inen'ibers provided with openings registi-able with each other, a sphere in one of the said openings for engaging the other opening so as to hold the movable member locked in relation to the stationary member, a pair of bolts'on the member having the sphere in its opening, one on each side of the opening, and a fiat spring held by one of said bolts and slidable on the other of said bolts and provided intern'iediate its ends with a pocket for receiving the sphere. i

In testimony whereof I afiix my signature.
